Microworm (Panagrellus redivivus) Starter Culture

The Ultimate Live Food for Tiny Fry & Newborns.

​Looking to safely raise tiny fish fry, newborn livebearers, or delicate nano species? Microworms are one of the easiest, most reliable, and highly prolific live foods you can culture right on your kitchen counter. They are physically smaller than newly hatched brine shrimp, making them the perfect "step-one" food for brand-new fry.
​Our Starter Pack contains a generous, active live culture booster—plenty of starter material to easily seed two full cultures simultaneously so you always have a backup running.
​What You Need to Setup (Per Culture)
​Container: A small, clean plastic food container (like a Tupperware or take-out container) with a tight-fitting lid.
​Media: Ordinary rolled oats or instant oatmeal.
​Yeast: A tiny pinch of standard active dry grocery store yeast.
​Water: Dechlorinated tap water or RO water.

​Everything You Need to Start Production Instantly
​Want to skip the grocery store run and get your live food factory running straight out of the box? Upgrade to our Microworm Master Kit. We provide the tools and our own specialized, low-odor recipe so you can culture with total confidence.
​What’s Included in the Master Kit:
​Production Container & Lid: A perfectly sized, clear-view plastic culture housing.
​YUMMY "Almost No Smell" Substrate: Our proprietary, custom-blended culture media. Formulated specifically to maximize worm yields while keeping the typical sour odor of traditional yeast/oat setups down to an absolute minimum.
​Fine-Tip Collection Brush: The perfect tool for neatly wiping clean, media-free worms off the container walls and swirling them directly into your fry tanks.
​Double-Strength Live Culture Starter: A generous portion of active microworms, packed with enough volume to easily seed two complete cultures.
​Master Kit Quick-Start Steps
​Step 1: Empty the proprietary YUMMY "Almost No Smell" substrate into your provided container.
​Step 2: Add water slowly and stir until the substrate reaches a thick, paste-like consistency (not swimming in standing water).
​Step 3: Use a pin, needle, or thumbtack to poke 4–5 tiny air holes into the lid for ventilation.
​Step 4: Add half of your live microworm starter to the center of the mix, snap the lid on, and keep it at room temperature. (Use the remaining starter to seed a second backup container at home!)
